What Is Molecule In Simple Words

What is molecule in simple words?

A group of two or more than two atoms of the same or different elements that are chemically bonded together is called a molecule. For example, two atoms of hydrogen and one atom of oxygen react with each other and form one molecule of water.

What’s a molecule in biology?

A molecule is the smallest unit of matter that has distinctive chemical and physical properties. A molecule owns a definite size and mass. Two or more atoms (same or different) held together by a chemical bond form a molecule wherein the ratio of two atoms is fixed in an element.

What are 3 types of molecules?

Molecules are of three types: Molecule of an atom, Molecule of an element and Molecule of a compound.

What do you mean by molecule answer?

(MAH-leh-kyool) The smallest particle of a substance that has all of the physical and chemical properties of that substance.

What is difference between atom and molecule?

Atom is the smallest particle of any element, whereas a molecule is the smallest particle of the compound. 2. Atoms may or may not present independently whereas molecules exist independently.

What is difference between molecule and compound?

A molecule is a group of two or more atoms held together by chemical bonds. A compound is a substance which is formed by two or more different types of elements which are united chemically in a fixed proportion. All molecules are not compounds. All compounds are molecules.

What is called molecule in chemistry?

A molecule is two or more atoms connected by chemical bonds, which form the smallest unit of a substance that retains the composition and properties of that substance. Molecules form the basis of chemistry. Molecules are noted with the element symbol and a subscript with the number of atoms.

Is DNA a molecule?

Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism. DNA is made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix.

Is water a molecule?

Atoms join together to form molecules. A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom. That’s why water is sometimes referred to as H2O. A single drop of water contains billions of water molecules.

Is glucose a molecule?

Glucose is a monosaccharide containing six carbon atoms and an aldehyde group, and is therefore an aldohexose. The glucose molecule can exist in an open-chain (acyclic) as well as ring (cyclic) form.

Is co2 a molecule?

CO2 is a molecule as well as a compound. More specifically, CO2 is considered a molecular compound. Compounds that contain atoms of different elements are called molecular compounds. CO2 consists of carbon and oxygen atoms.

Is DNA bigger than an atom?

A typical atom is anywhere from 0.1 to 0.5 nanometers in diameter. DNA molecules are about 2.5 nanometers wide.
